Description

Explosion proof double girder overhead crane is a special design bridge crane type. The main purpose of this overhead crane is for inflammable and explosive environments, with high safety and reliability.

It includes double main beams, end beams, lifting mechanism of the hoisting trolley, operating mechanism, electrical control system. It also has a cabin room, safety devices, tracks, explosion-proof components and auxiliary equipment. Explosion proof bridge crane is suitable for places in factories where the explosion-proof capacity is not higher than IIB or IIC level and the detonation temperature group is T1 to T4, where there is an explosive gas mixture formed by flammable gas or steam and air.

Application

  • Petrochemical: For equipment installation, maintenance and material handling in flammable and explosive environments.
  • Coal Mine: Carry out heavy equipment handling and installation in gas and dust environments.
  • Pharmaceutical manufacturing: Transport raw materials and products in areas with high explosion-proof requirements.
  • Food processing: Mainly for material handling in dust explosion-proof environments.
  • Aerospace: Handling and installing large parts in flammable and explosive areas.
  • Electricity: Install and maintain equipment in flammable and explosive environments.
  • Warehousing and logistics: Carry dangerous goods in warehouses with high explosion-proof requirements.

Features

  • Explosion-proof design: In conjunction with an explosion-proof electric hoist, all electrical components and coils are in an explosion-proof housing.
  • Double-beam structure: The double-beam design has strong load-bearing capacity and stable operation, which is suitable for large-tonnage lifting needs.
  • Strong durability: High-quality components are used to ensure long-term stable operation of the equipment in harsh environments.
